Australian Energy Market Operator

AEMO operates Australia's National Electricity Market (NEM), the interconnected power system in Australia’s eastern and south-eastern seaboard, and the Wholesale Electricity Market (WEM) and power system in Western Australia.

AEMO operates gas retail markets in New South Wales and the Australian Capital Territory, Queensland, South Australia, Victoria, and Western Australia. AEMO also operates wholesale gas markets in south-eastern Australia, those being the Declared Wholesale Gas Market in Victoria (DWGM), the Short Term Trading Market in Adelaide, Brisbane and Sydney (STTM), and the Gas Supply Hub (GSH), whose trading locations are based at Wallumbilla in Queensland, and Moomba in South Australia. AEMO also operates the Natural Gas Services Bulletin Board (GBB), and is system operator of the Victorian Gas Declared Transmission System. AEMO is also responsible for Gas Services Information functions in Western Australia.

AEMO gives notice of consultation on proposed changes to the STTM Procedures for the Short Term Trading Market (STTM) and GBB Procedures for the Natural Gas Services Bulletin Board (GBB) under rule 135EE of the National Gas Rules.
This notice of consultation is dated 4 August 2015.

Proposed procedure changes

The proposed change to the STTM Procedures (section 2.2) is to:

Add a new Custody Transfer Point (CTP) at EGP Wilton for the Sydney hub. AEMO proposes adding the CTP to reflect Jemena EGP’s upstream gas infrastructure developments that will connect to the Sydney network.

The proposed change to the GBB Procedures (Schedule 2) is to:

Amend Sydney (SYD) Demand Zone description in Schedule 2 – Demand and Production zones to include EGP Wilton CG to reflect these gas infrastructure developments and wording change in SYD Demand Zone description to reflect the correct CGs and loads for SYD Demand Zone. This will allow gas delivered through EGP to SYD Demand Zone to be captured in SYD Demand Zone.

AEMO has published an Impact and Implementation Report (IIR) below, which details the proposed changes to the STTM and GBB Procedures.
